How It Works

1

Install & Run

Single binary. One command. 10 seconds for quick profile, 60 for deep analysis.

2

Get Diagnosis

Health score, anomalies with severity, root cause chain. JSON for AI, human-readable summary.

3

Fix & Verify

Copy-paste sysctl commands. Run again. Diff shows what improved.

Quick Start Guide

🔍 37 Anomaly Rules

Rate-based detection. Catches TCP retransmits, page reclaim, THP splits, NUMA misses, conntrack overflow — problems happening right now.

🩺 Health Score

Single 0-100 number based on USE methodology. AI agents use it to decide next steps. Humans use it to prioritize.

🔧 Copy-Paste Fixes

35 recommendations with exact sysctl commands, evidence, and citations. Each tagged as "fix" or "optimization".

🤖 MCP Server

Claude Desktop and Cursor connect via stdio and diagnose servers interactively. No file juggling.

🖥️ GPU & PCIe

Detects NVIDIA GPUs, maps PCI devices to NUMA nodes, flags cross-NUMA GPU-NIC pairs (30-50% DMA penalty).

📊 67 BCC Tools

~84% of Brendan Gregg's BPF toolkit in one binary. Histograms, events, stack traces, flame graphs.

🧠 NUMA & THP

Page reclaim rates, compaction stalls, THP splits, NUMA miss ratio. The invisible latency killers.

📚 22 Chapters

Book-level documentation in English and Russian. From Linux fundamentals to production tuning checklist.

🔒 Single Binary

No dependencies. No config. No YAML. Cross-compile from macOS, deploy anywhere. Apache 2.0 licensed.
